Description

Technical Field

[0001] The invention relates to the technical field related to alanine production crystallization, and in particular to an alanine production crystallization evaporator. Background Art

[0002] Alanine is white crystal or crystalline powder, no odor, with sweet taste. It has stable chemical properties and is easily soluble in water (16.5%, 25℃). During the production process of alanine, it needs to be evaporated and crystallized. The evaporation crystallization operation refers to heating and evaporating the solvent to change the solution from unsaturated to saturated. If the evaporation continues, the excess solute will precipitate as crystals. The evaporation crystallization technology can also be used in seawater desalination, chemical industry, salt production, oil fields, biofuels, chemical industry, power generation, papermaking, chlor-alkali, metal mining and other industries. The existing evaporation crystallization method mainly uses stirring and heating, and then collects the crystals produced by heating.

[0003] However, the following problems are often encountered in the existing evaporation crystallization process:

[0004] The existing stirring structure is usually a single-axis body that rotates in a circumferential direction, and the stirring area is limited, which is not conducive to comprehensive stirring, reduces the crystallization efficiency, and is difficult to collect the crystals attached to the evaporating dish structure, resulting in some crystals not being collected. With the addition of the next batch of liquid alanine, these crystals are re-dissolved in water, and the collection rate is reduced. In addition, the dissolution of the previous batch of alanine increases the amount of alanine in the current liquid, prolongs the evaporation time, and reduces the crystallization efficiency. The present application designs an alanine production crystallization evaporator to solve the above defects. Summary of the invention

[0005] In order to achieve rapid stirring and evaporation of liquid materials and timely output of evaporated crystals, the present application provides an alanine production crystallization evaporator.

[0007] A crystallization evaporator for producing alanine comprises an outer shell, a heating dish module is arranged at the inner bottom end of the outer shell, a sealing cover is embedded in the upper end of the outer shell, a fixing frame is arranged at the upper end of the sealing cover, a gas conveying module is arranged inside the fixing frame, an electric rotating disk is arranged at the lower end of the fixing frame, wiping components are evenly arranged along the circumference of the edge of the electric rotating disk, a rotating shaft capable of conveying gas is arranged at the middle part of the electric rotating disk, a stirring component is evenly arranged along the circumference of the lower end of the rotating shaft, and an outlet component is evenly arranged along the circumference of the outer shell.

[0008] The rotating shaft includes a shaft body, a deep cavity, hole one, and hole two. The shaft body is installed at the lower end of the electric rotating disk, and the extending tube passes through the electric rotating disk and extends into the deep cavity opened in the shaft body. In the lower half of the deep cavity, hole one and hole two are successively opened from top to bottom. The ventilation conditions of hole one and hole two are controlled by the lifting of the partition member. When the partition member is in the initial position (the lowest position), hole one is in the open state and hole two is in the closed state. At this time, the gas input by the gas delivery module enters the connection cavity through hole one, thereby blowing the pneumatic member to rotate, so that the synchronously rotating stirring member stirs the liquid material. When the partition member rises to the highest position (the upper end of the heating dish module abuts against the lower end of the connecting frame), hole one is in the closed state and hole two is in the open state. At this time, the gas input by the gas delivery module enters the interior of the housing through hole two, thereby blowing the crystals, and cooperating with the scraping at the bottom end of the connecting frame, so as to scrape off the attached crystals, and then blow out the crystals through air blowing.

[0009] The stirring assembly includes a connecting frame, a connection cavity, a pneumatic member, a stirring member, a stirring rod, and a partition member. The connecting frame is installed on the outer wall of the shaft body. The connection cavity opened inside the connecting frame is aligned with the position of hole one, and pneumatic members are evenly arranged in the connection cavity.

The diameters of the rubber column and the shaft body are equal, and the rubber column is sleeved in a through hole opened in the middle of the heating dish in a vertically sliding manner. The rubber column is sleeved in the through hole, which not only ensures the sealing performance but also ensures that the heating dish can slide up and down in a sealed state.

[0014] As a preferred technical solution of the present invention, the pneumatic member includes a rotating column and a blowing fan.

A guiding member located at the side end of the rotating column is installed inside the connecting cavity.

[0015] As a preferred technical solution of the present invention, the stirring member includes a connecting sleeve, an inner cylinder, and stirring paddles. The connecting sleeve is connected to the lower end of the rotating column. The inner cylinder is slidably arranged up and down inside the connecting sleeve. When the upper surface of the heating dish abuts against the lower end of the connecting frame, the inner cylinder retracts into the connecting sleeve, and the synchronously rising stirring paddles will not affect the contact between the heating dish and the connecting frame. Stirring paddles are installed outside the inner cylinder.

[0016] As a preferred technical solution of the present invention, the stirring rod includes a movable head, a connecting head, a rod body, and a built-in spring.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. An alanine production crystallization evaporator according to the present invention. In this application, the evaporation of liquid materials is stirred with multiple degrees of freedom, which improves the stirring area and the degree of stirring uniformity. For the problem of crystal retention generated after evaporation, the crystals are centrally collected by means of scraping + air blowing.

[0022] 2. An alanine production crystallization evaporator according to the present invention. The setting of the rotating shaft drives the stirring component to rotate circumferentially on the one hand, so that the stirring piece and the stirring rod are in overall large-scale rotation. On the other hand, the ventilation conditions of the first hole and the second hole in the rotating shaft control the air delivery trajectory. The ventilation conditions of the first hole and the second hole are controlled by the lifting of the partition piece. It is ensured that when stirring, gas enters the connection cavity from the opened first hole, thereby blowing the pneumatic piece to rotate. The synchronously rotating stirring piece stirs the liquid material, and it is ensured that when collecting crystals, gas is ejected from the opened second hole, thereby blowing out the crystals inside the housing by air blowing;

[0023] 3. An alanine production crystallization evaporator according to the present invention. The stirring piece and the stirring rod in the stirring component move circumferentially as a whole, but are individual units. The stirring piece is in a single-rotation state, and the stirring rod is in a random swinging state, so that the stirring component presents multi-degree-of-freedom angle adjustment;

[0024] 4. An alanine production crystallization evaporator according to the present invention. For the crystal particles attached to the heating dish, in this application, the heating dish is raised so that the upper end surface of the heating dish contacts the lower end surface of the connecting frame. At this time, the lower part of the connecting frame acts as a scraping structure. As the electric rotating disk continues to rotate, the connecting frame is driven to scrape the crystal particles on the heating dish, and the scraped crystals are blown by the gas ejected from the second hole, so that the crystals are blown into the existing collection equipment from the opened outlet position.

[0033] The embodiments of the present invention are described below with reference to the accompanying drawings. In the process, in order to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0034] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0035] like Figures 1 to 7 As shown, a crystallization evaporator for alanine production comprises a shell 1, a heating dish module 2 is arranged at the inner bottom end of the shell 1, a sealing cover 3 is embedded in the upper end of the shell 1, a fixing frame 4 is arranged at the upper end of the sealing cover 3, a gas delivery module 5 is arranged inside the fixing frame 4, an electric rotating disk is arranged at the lower end of the fixing frame 4, a wiping assembly 6 is evenly arranged along the circumference of the edge of the electric rotating disk, a rotating shaft 7 for conveying gas is arranged in the middle of the electric rotating disk, a stirring assembly 8 is evenly arranged along the circumference of the lower end of the rotating shaft 7, and an outlet assembly 9 is evenly arranged along the circumference of the outer shell 1.

[0036] The rotating shaft 7 includes a shaft body 71, a deep cavity 72, a first hole 73, and a second hole 74. The shaft body 71 is installed at the lower end of the electric rotating disk, and the extending pipe 53 passes through the electric rotating disk and extends into the deep cavity 72 opened in the shaft body 71. The lower half of the deep cavity 72 is successively provided with the first hole 73 and the second hole 74 from top to bottom. The ventilation of the first hole 73 and the second hole 74 is controlled by the lifting of the partition member 86. When the partition member 86 is in the initial position (the lowest position), the first hole 73 is in an open state and the second hole 74 is in a closed state. At this time, the gas input by the gas delivery module 5 enters the connection cavity 82 through the first hole 73, thereby blowing the pneumatic member 83 to rotate, so that the synchronously rotating stirring member 84 stirs the liquid material. When the partition member 86 rises to the highest position (the upper end of the heating dish module 2 abuts against the lower end of the connection frame 81), the first hole 73 is in a closed state and the second hole 74 is in an open state. At this time, the gas input by the gas delivery module 5 enters the interior of the housing 1 through the second hole 74, thereby blowing the crystal, and cooperating with the scraping at the bottom end of the connection frame 81 to scrape off the attached crystal, and then blowing out the crystal through air blowing.

[0037] The stirring assembly 8 includes a connection frame 81, a connection cavity 82, a pneumatic member 83, a stirring member 84, a stirring rod 85, and a partition member 86. The connection frame 81 is installed on the outer wall of the shaft body 71. The connection cavity 82 opened inside the connection frame 81 is aligned with the position of the first hole 73, and the pneumatic member 83 is uniformly arranged in the connection cavity 82. The lower end of the pneumatic member 83 is provided with a telescopic stirring member 84. The connection frame 81 is uniformly provided with hidden grooves, and the stirring rod 85 is slidably arranged in the hidden grooves. When the upper end of the rising heating dish module 2 abuts against the lower end of the connection frame 81, the stirring rod 85 is hidden in the hidden groove, and there is an interval between the stirring rod 85 and the stirring member 84. The partition member 86 is slidably arranged up and down at the side end of the rotating shaft 7, and the partition member 86 is used to control the ventilation of the first hole 73 and the second hole 74.

[0038] Specifically, the liquid material is injected into the outer shell 1. After injection, the liquid material is placed on the heating dish module 2 for heating treatment. At the same time, the wiping component 6 and the connecting frame 81 are driven to rotate by the electric rotating disk. The rotating wiping component 6 wipes the water vapor adhering to the sealing cover 3 (the water vapor is mainly discharged through the gas delivery module 5, and a small amount of water vapor may adhere to the inner wall of the sealing cover 3). The rotating connecting frame 81 drives the stirring member 84 and the stirring rod 85 to rotate circumferentially. Under the elastic action, the stirring rod 85 is in an irregular shaking state while maintaining the circumferential rotation as a whole, thereby accelerating the stirring speed. And the stirring member 84 is in a rotating state under the cooperation of the pneumatic member 83 and the air blowing (the gas delivery module 5 delivers the gas into the deep cavity 72, and after passing through the first hole 73, it enters the connecting cavity 82, and the air blowing drives the pneumatic member 83 to rotate so that the stirring member 84 rotates synchronously), which also accelerates the stirring speed. After evaporation and crystallization, with the rise of the heating dish module 2, the partition member 86 is synchronously lifted after being squeezed until the upper end surface of the heating dish module 2 contacts the lower end surface of the connecting frame 81. At this time, the outlet assembly 9 is opened, the first hole 73 is closed, and the second hole 74 is opened (the blowing direction of the gas is towards the upper end surface of the heating dish module 2). With the continuous rotation of the electric rotating disk, the connecting frame 81 shovels the crystals on the heating dish module 2 and blows the crystals into each opened outlet assembly 9 (the outlet assembly 9 is connected to the existing collection device) under the action of the air blowing, so as to blow the crystals into the existing collection device. Subsequently, the heating dish module 2 descends and resets, and the next batch of liquid material is injected. This application performs multi-degree-of-freedom stirring on the evaporation of the liquid material, accelerating the stirring rate, and for the problem of crystal retention after evaporation, the crystals are centrally collected by the method of scraping + air blowing.

[0039] In another embodiment provided by the present invention, further, the heating dish module 2 includes a heating dish 21, a heating layer 22, a connecting frame 23 and a cylinder 24. The heating layer 22 is arranged at the lower end of the heating dish 21, the heating layer 22 is installed inside the connecting frame 23, and a cylinder 24 is connected between the connecting frame 23 and the bottom end of the outer shell 1.

[0040] Specifically, the heating layer 22 can heat the heating dish 21, thereby evaporating and crystallizing the liquid material on the heating dish 21. After crystallization, the cylinder 24 drives the heating dish 21, the heating layer 22 and the connecting frame 23 to rise as a whole until the upper surface of the heating dish 21 abuts against the lower end of the connecting frame 81.

[0041] Further, the gas delivery module 5 includes an output pump 51, an input pump 52, and an extension pipe 53. The output pump 51 installed on the left side of the upper end of the fixed frame 4 is communicated with an output cavity opened inside the fixed frame 4. The input pump 52 installed on the right side of the upper end of the fixed frame 4 is communicated with an input cavity opened inside the fixed frame 4, and the lower end of the input cavity is connected to the extension pipe 53.

[0042] Specifically, the steam generated inside the housing 1 is sucked into the output cavity and discharged outward by the air suction of the output pump 51. The outside air is sucked into the extension pipe 53 by the input pump 52, and then enters the deep cavity 72. The sucked air can be used for the blowing of the subsequent pneumatic component 83 and the air blowing output of the crystal.

[0043] Further, the wiping assembly 6 includes a connecting rod 61 and a wiping sleeve 62. The inner end of the connecting rod 61 is installed on the edge of the electric rotating disk. A wiping sleeve 62 is sleeved on the connecting rod 61, and the wiping sleeve 62 is in contact with the inner wall of the sealing cover 3.

[0044] Specifically, the electric rotating disk drives the connecting rod 61 to rotate, so that the wiping sleeve 62 wipes the water vapor attached inside the sealing cover 3, avoiding the situation of dripping after accumulation.

[0045] Further, a rubber column is provided at the lower end of the shaft body 71. The diameter between the rubber column and the shaft body 71 is equal, and the rubber column is slidably sleeved up and down in a through hole opened in the middle of the heating dish 21. The rubber column is sleeved in the through hole, which ensures the sealing performance and also ensures that the heating dish 21 can slide up and down in a sealed state.

[0046] Further, the pneumatic component 83 includes a rotating column 831 and a blowing fan 832. The rotating column 831 is rotatably arranged in the connecting cavity 82. A blowing fan 832 is sleeved on the rotating column 831. A guiding member 87 located at the side end of the rotating column 831 is installed inside the connecting cavity 82.

[0047] Further, the stirring component 84 includes a connecting sleeve 841, an inner cylinder 842, and stirring paddles 843. The connecting sleeve 841 is connected to the lower end of the rotating column 831. The inner cylinder 842 is slidably arranged up and down inside the connecting sleeve 841. When the upper surface of the heating dish 21 abuts against the lower end of the connecting frame 81, the inner cylinder 842 retracts into the connecting sleeve 841, and the stirring paddles 843 that rise synchronously will not affect the contact between the heating dish 21 and the connecting frame 81. Stirring paddles 843 are installed outside the inner cylinder 842.

[0048] Specifically, the gas entering the connecting cavity 82 blows the blowing fan 832 when passing through it, causing the entire pneumatic component 83 to rotate, thereby driving the stirring component 84 to rotate synchronously, and further stirring and evaporating the liquid material on the heating dish 21.

[0049] Further, the stirring rod 85 includes a movable head 851, a connecting head 852, a rod body 853, and a built-in spring 854. The movable head 851 is slidably arranged up and down in the hidden groove. A ball hinge is provided between the movable head 851 and the connecting head 852. The lower end of the connecting head 852 is installed with the rod body 853. The built-in spring 854 that annularly surrounds the connecting head 852 is connected between the movable head 851 and the rod body 853. A rubber sleeve is connected between the movable head 851 and the rod body 853, and the connecting head 852 and the built-in spring 854 are located inside the rubber sleeve. The rubber sleeve serves to flexibly connect the movable head 851 and the rod body 853, avoiding the direct contact between the liquid material and the built-in spring 854.

[0050] Specifically, due to the ball hinge connection between the movable head 851 and the connecting head 852, the up-and-down sliding connection of the movable head 851, and the annular arrangement of the built-in spring 854, the degree of freedom of the rod body 853 is greatly improved. When the stirring rod 85 rotates following the connecting frame 81, the rod body 853 swings irregularly on the liquid material on the heating dish 21, thereby accelerating the stirring rate.

[0051] Further, the partition member 86 is successively provided with a docking hole 88 and an alignment hole 89 from top to bottom. The docking hole 88 at the initial position is aligned and connected with the hole one 73, and the hole two 74 and the alignment hole 89 at the initial position are arranged in a vertically staggered manner. The ventilation of the hole one 73 and the hole two 74 is controlled by the lifting of the partition member 86. When the partition member 86 rises to the highest position, the docking hole 88 is staggered from the hole one 73, and the alignment hole 89 is aligned with the hole two 74.

[0052] Further, the outlet assembly 9 includes a discharge port 91, an alignment plate 92, and a resisting member 93. Exits are uniformly opened on the outer circumference of the housing 1. The discharge port 91 is externally aligned and installed at the exit. A movable groove is opened at the side end of the housing 1. The alignment plate 92 is slidably arranged up and down inside the movable groove. The lower end of the alignment plate 92 is installed with the resisting member 93. The resisting member 93 contacts the outer edge of the heating dish 21. The alignment opening opened by the alignment plate 92 at the initial position is arranged in a staggered manner with the exit.

[0053] Specifically, the air cylinder 24 drives the heating dish 21, the heating layer 22, and the connecting frame 23 to rise as a whole. The rising heating dish 21 drives the alignment plate 92 and the resisting member 93 to rise as a whole until the upper surface of the heating dish 21 abuts against the lower end of the connecting frame 81. At this time, the alignment opening is aligned with the exit position, and the exit is in an open state.

[0054] Working process:

[0055] Step 1: Inject the liquid material into the housing 1 so that it drips onto the heating dish 21;

[0056] Step 2: Heat the liquid material on the heating dish 21 through the heating layer 22. At the same time, drive the wiping assembly 6 and the connecting frame 81 to rotate through the electric rotating disk. The wiping assembly 6 in the rotating state wipes the water vapor adhering to the sealing cover 3, and the rotating connecting frame 81 drives the stirring member 84 and the stirring rod 85 to perform multi-degree-of-freedom stirring, so as to stir the liquid material until it is completely evaporated into alanine crystals;

[0057] Step 3: After evaporation and crystallization, drive the heating dish 21, the heating layer 22, and the connecting frame 23 to rise as a whole through the cylinder 24 (the lower end of the heating dish 21 presses against the lower end of the partition member 86 so that the partition member 86 rises synchronously) until the upper surface of the heating dish 21 abuts against the lower end of the connecting frame 81. At this time, the docking hole 88 is offset from the hole one 73, the alignment hole 89 is aligned with the hole two 74, and the hole two 74 is in the open state (the gas in the deep cavity 72 blows out from the hole two 74 to perform air blowing and conveying on the crystals on the heating dish 21), and the alignment port is aligned with the outlet position (the outlet is open);

[0058] Step 4: As the electric rotating disk continues to rotate, the lower end of the connecting frame 81 shovels off the crystals adhering to the heating dish 21, and under the action of air blowing, blows the crystals into the open outlet, so as to blow the crystals into the existing collection equipment;

[0059] Step 5: After the crystals are completely collected, the heating dish module 2 descends and resets. At this time, the opening is closed, the hole two 74 is closed, and the hole one 73 is open. Repeat the above steps to perform evaporation and crystallization on the next batch of liquid materials.

[0060] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
